Lewis is charged with second-degree murder after the medical examiner's lab matched DNA evidence from the crime scene and Vetrano to the suspect, police said.

Lewis is being held without bail. A grand jury could issue a formal indictment soon.

Meanwhile, Vetrano's family is taking steps to honor her memory. They went to Cuba last month, where Vetrano had planned to run a November marathon. They sprinkled some of her ashes in a quiet park.

Her father, Philip Vetrano, said he has disbursed nearly $300,000 in GoFundMe donations made in Karina's honor. So far, the donations have included a check to Archbishop Molloy High School for a scholarship in Karina's honor, according to the GoFundMe page.
